Specification of Letters Patent.

Patented Jane 1, 1920.

Application filed November 5, 1917. Serial No. 200,471.

To all whom it may concern: 7

Be it known that I, FRED Ross a cit zen of the United States, residing at Iapilhon, in the county of Sarpy, State of Nebraska, have invented certain new and useful Improvements in Garbureter Controls; and I do hereby declare the followingto be a full,

clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to auxiliary throttle control devices for automobiles.

The object of the invention is to provide a controlling device for the throttles of automobile engines which will permit the actuation of a throttle valve of a carburetor from the front of the car, that is in front of the radiator when the car is being cranked, so that while the throttle may be opened wide for starting purposes, it may be quickly closed for moderate speed of the engine as soon as the latter has been started. This obviates the necessity of the driver of the car rushing from the front of the car, after cranking the engine, to stop the engine from racing after it has started.

With the above objects in view, and such others relating to the details of construction, as may hereinafter appear, my invention will now be fully set forth and described, reference being had to the accompanying drawings.

In the drawings Figure 1 is a general view showing the application of my invention to an automobile.

Fig. 2 is an enlarged plan view of the attachment.

Fig. 3 is an edge view of the same in place.

Fig. 4 is a perspective View of the auxiliary lever plate constituting part of the attachment.

Fig. 5 is a plan view of a modified form, and

Fig. 6 is an edge thereof.

Referring more particularly to the drawings, 1 represents the carbureter from wlnch extends the throttle stem 2. Supported on the throttle stem 2 is the throttle arm 3 to which is connected the link 4 which extends to the opposite side of the engine, and is there operatively connected to the steering post throttle lever in a usual manner, the steering post mechanism not being shown. Also, the hub of the throttle arm has an extension 5 which is split and provided with a threaded aperture into which the adjusting screw 6 extends, the function of the latter being to strike against the stop 7 on the carburetor casing to limit the movement of the throttle valve to closing position, whilea nose l1 ofthe hub limits its movement in the other direction. The setscrew 8 passes through the legs ofthe split extension 5 in the usual manner to secure the adjusting screw in its positions of adjustment. H r p The parts above described are common to a certain type of carburetors. In carrying out the present invention, a. plate 9 is shaped to overlie the hub of the throttle arm and the extension 5, one extremity of the plate 9 being bent into an angular flange 10 which is crimped as shown and fits into the angle between the throttle arm and the nose 11 extending from the hub of the throttle arm, when the plate 9 extends across the hub and the extension. In applying the plate 9, the set-screw 8 is removed, so that the plate may lie flat against the extension, after which the set-screw is passed through an aperture 12 in the plate, which registers with the threaded socket in which the set-screw normally seats. In this manner, the plate 9 is looked upon the throttle arm in rigid rela tion thereto by means of a single securing device, the extremity of the plate 9 extends a suitable distance beyond the hub of the throttle arm in a direction which is lateral to the position of the engine, so that an actuating movement longitudinally of the engine will swing the plate 9 to actuate the throttle valve. Extending toward the front of the car, and longitudinally of the engine is a rod 13 whose rear end may be engaged with any one of a plurality of openings 14 formed along the outer end of the plate 9. The other end of the rod 13 extends through and beyond the front of the radiator, where it is provided with a suitable ring 15 for the convenient manipulation of the rod.

By the use of the above attachment, when the engine is being cranked, the operator may regulate the throttle valve to wide open position, and then may immediately close the throttle to cut down the speed of the engine to prevent its racing, the operator being enabled to do this without running from the front of the car to the drivers seat to manipulate the steering post throttle lever.

As 'a modified form of the invention, the extension or attachment arm may be formed as an integral part of the extension 5, the auxiliary throttle arm 16 being formed as a continuation of one of the-split sections of the extension 5, and having at its outer end an eye 17 within which the rod 13 may be engaged. In the application of the invention in its modified form, the usual throttle arm is removed from the throttle stem, and the two-armed structure substituted therefor, the connections to the steering post throttle lever and to the auxiliary throttle controlling device at the front of the car being then made as above described.

It will be apparent from the foregoing description that the attachment device or auxiliary control mechanism will constitute a valuable and practical means for preventing the undue racing of an engine, and will furthermore be a source of convenience to the operator, in that he will be able to regulate the carburetor without being required to run around the car in order to cut down the throttle when the engine is racing.

WVhat I claim as my invention is In combination with a carburetor whose stem carries a hub having a lateral arm, an upstanding nose, and a depending split extension, and a set screw through the legs of the extension; a plate adapted to lie against the nose, hub, and extension and to extend part way along the arm, one end having an angular flange hooking over the nose and arm and its body having holes whereof one receives said set screw, and a rod engaged with another hole and led to a distant point.

In testimony whereof, I afiix my signature in the presence of two witnesses.

FRED ROSS.
